Hi Riley,
I am also looking to build an Airdrome Sopwith Pup, so have one or two contacts.
Firstly, TAVAS founder Andrew Carter, who has a Fokker Triplane - see www.tavas.com.au for contact details.
Secondly, there are a number of people who have both completed or are currently building Airdrome kits at Watts Bridge. Bruce Clarke has a Sopwith Pup, and
I believe is now building a Nieuport. Others have a Fokker Eindekker, and Sopwith Camel under construction.
If you PM me (ie start a "conversation" ) I can give you emails (but don't want to put them here in public threads).
Good luck!
Neil
